inlinestatic

Computes the intersects predicate between a PreparedLineString and a Geometry.

Parameters

prep	the prepared linestring
geom	a test geometry

Returns: true if the linestring intersects the geometry

Here is the caller graph for this function:

bool geos::geom::prep::PreparedLineStringIntersects::intersects ( const geom::Geometry * g ) const

Tests whether this geometry intersects a given geometry.

Parameters

g	the test geometry

Returns: true if the test geometry intersects

bool geos::geom::prep::PreparedLineStringIntersects::isAnyTestPointInTarget ( const geom::Geometry * testGeom ) const

protected

Tests whether any representative point of the test Geometry intersects the target geometry. Only handles test geometries which are Puntal (dimension 0)

Parameters

testGeom a Puntal geometry to test
